摘　　要：根据北方地区城市景观水体的特点以西安某景观湖为例,进行了表流-潜流组合的人工湿地水处理试验。结果表明,表流区对COD、藻类和SS有很好的去除效果,减少了潜流区基质堵塞的几率,再经过潜流区COD、藻类、SS去除率分别达到80%以上;TN、TP、NH3-N主要在潜流区去除,平均去除率分别为63.7%、65.8%、79.7%。表流-潜流组合的人工湿地适合于北方地区城市景观水体的处理,为该地区构建人工湿地提供了理论依据和设计参照。According to the surrounding condition and water quality of urban landscape water in northern China, taking Yanming lake for example, the combination of surface and subsurface flow constructed wetland was conducted. It was found that the removal ratio of COD, algae, and SS in the surface flow area were 63.7%, 65.8%, and 79.7% respectively, which could effectively prevent the substance blocking in the following subsurface flow area. Comparing with COD, algae, and SS, the removal rate ofTN, NH3-N, and TP in the subsurface flow area was 63.7%, 79.7%, and 65.8%, respectively. The results show that the wetland system was feasible for urban landscape water quality restoration in northern China.
